[Serusers] [Users] Re: usrloc loading

[Daniel-Constantin Mierla]

Hello,

some confusion was created around this subject. It was pointed a news 
which was related to an improvement (fetch support) which brought memory 
usage optimization in usrloc (going to be expanded in usage to other 
modules, like lcr, presence ...), not usrloc loading/lookup 
optimization. It was not yet a news since the work is not fully 
finished/well tested. The news about this new improvements will come in 
the near future. It started in summer, with:

http://openser.org/pipermail/devel/2006-July/003469.html

Shortly, usrloc records are not loaded anymore by the main process, but 
by first child. All other children processes can handle other events/sip 
messages in parallel. Previously, at start, OpenSER was blocked until 
all records were loaded, which could be quite long when having big 
numbers of active users.

Cheers,
Daniel
